To ALL WHoM In: MAY concourt:

Be it known that'I, LE'VI S. ENOS, of the4 town of Almond, in the county of Allegany, in the State of New York, (assigner to George W. Stearns and William H. Prior,) havel invented a certain 'new 'and'useful Improve- -Inent inStove-Pipe Dampers; and the following is a full, clear, and exact description of the same,| reference being had to the accompanying drawings, making a part of this specification, in whichl Figure 1 represents a vertical section through the stove-pipe, `showing an edge viewof the damper, and a Hat view ofthe rack for operating it and holding it in any desired position. d

Figure 2 shows a. flat view of the oval damper. g

The object of my invention is to regulate the draught by an 'inclined plate-damper'i'n the stoveipipe; and it consists in the simple arrangement of serrated latch connected with van oval plate, the latch being provided with a ring to operate it with, and a spring to hold the notched latch in any desired position.

To enable others to make and use my invention, 'I will describe it more in detail, referring to the drawings, and to the letters marked thereon. i y

In the stovepipe A, I t an oval plate, B, and hinge it centrally with buttons b b. To one sidev of the plate B, I secure a projecting piece, d, to which is pivoted the latch C, which I make of roll .brass or other Iilatemetal of suitable thickness, the outer end forming a ring, D, the straight or ,curved portion being notched or serrated on one ofits edges, c c, to catch on a metal plate, d, through which it passes to hold the damper-plate Bin any desired position. When the notches are on the top edge of the latch C, it requiresthe attachment'ofla spring,

e, to hold the notches in the plate d, as shown in viig. 1; but by reversing the latch, and-having the sel-rations on the under edge, lthe spring e may be dispensed'with, as the latch will hold the damper'in any required posi- .tion by its owngravity.y l v d What 'I claim as my. invention, and desire to secure by Letters Patent, s#-

The serrated latch C, as constructed and arranged, in combination with the oval-plate damper B, substantallyas and for the purposes herein set forth.

In` testimony whereof, I hereunto subscribe my 11eme, in the presence ofy LEVI S, ENOS.
